Actually yes. Scraped Vista off my home PC (running the 7 pill now) I'm a happy man. I work with XP at office, and there's no trace of Vista, any more in my life. Happy man, me. 
Did I mention that I'm a happy man?

Whereas soon I'm going to start using Vista for the first time  I have two PCs on my desk @ work. One's my 'corporate network' PC...that I use for e-mail and....well, e-mail really. That currently runs Windows 2000 (yep, you read that right) like the thousands of other employees here. We got an e-mail yesterday basically saying that over the next 3-6 months, Vista and Office 2007 would be rolled out to our PC estate. I have to say I'm really looking forward to using Vista on a poxy old Pentium 4 PC with 1GB of RAM. My co-worker, with a 2.2GHz Celeron and 512MB of RAM is looking forward to it even more
My second PC @ work currently runs XP. If I could be bothered, I'd upgrade to Weven. But it works, so I probably won't...for a while. Got a Weven VM, though.
At home, it's OS X all the way, apart from my Weven VM that I use to run Visual Studio (and Office on the rare occasion that iWork isn't enough for working with Office docs).

Good luck with your new endeavour. It's going to be one hell of a ride.

I'm thinking of a little wager on how far through the boot process it gets before the machine gives up under the strain of the unfair challenge

I am implementing MODBUS protocol. I want to try my C/C++ program between serial port and USB port on single PC before executing code in microcontrollers. Please give me some hint!!!
|
|
|
|
|
There are many many MODBUS resources on the web, see, for instance, here.
CodeProject has some MODBUS related articles too [^].

Hi,
I am looking for a C++ library for 3D data visualisation. The main features that I'm looking for are
1. Capability to handle large data sets(MB's to few GBs)
2. Interactive 3D visualisation
3. Slicing through the data cube
4. Real time visualisation from buffer without having to save data to hard disk
Could anyone please suggest me some good libraries(both Open source or non open source)?
Thanks in advance.

Hey, im doing some client/server stuff in a windows service. Pretty much new to this stuff using Visual C++ 6
The problem I'm encountering is that when I try to stop the service through Service Manager, it crashes. I added some MessageBoxes code, to trace where they are crashing and I found that when it closes the listener socket it crashes!!!
I tried to run the service as a console application, and by myself called the function which is called SERVICE__CONTROL__STOP event is received so that I may reproduce the bug and debug easily. But it is working fine. The windows service is only crashing when I stop it through Service Manager
Here is some code
The main function
int main(int argc, char* argv[])
{
CTestService CustomServiceObject;
if (!AfxWinInit(::GetModuleHandle(NULL), NULL, ::GetCommandLine(), 0))
{
std::cerr << "MFC failed to initialize!" << std::endl;
return 1;
}
if (! CustomServiceObject.ParseStandardArgs(argc, argv))
{
CustomServiceObject.StartService();
}
return CustomServiceObject.m_Status.dwWin32ExitCode;
}
The Service Handler callback function
void CNTService::Handler(DWORD dwOpcode)
{
CNTService* pService = m_pThis;
pService->DebugMsg("CNTService::Handler(%lu)", dwOpcode);
switch (dwOpcode) {
case SERVICE_CONTROL_STOP:
pService->SetStatus(SERVICE_STOP_PENDING);
pService->OnStop();
}
the OnStop() function
void CTestService::OnStop()
{
m_sListener.ShutDown(2);
m_sConnected.ShutDown(2);
MessageBox(NULL, "After Shutdown", NULL, IDOK);
m_sConnected.Close();
MessageBox(NULL, "Closed connected socket", NULL, IDOK);
m_sListener.Close();
MessageBox(NULL, "Closed listener socket", NULL, IDOK);
::PostThreadMessage(m_dwThreadID, WM_QUIT, NULL, NULL);
MessageBox(NULL, "After PostThreadMessage", NULL, IDOK);
}
Moreover, I compiled the code in in VC2008, compiled fine, without any changes and the above code was running fine as expected but only in Release build. In Debug build, I couldn't even start the service, instead got an error that the service does not respond to control requests in a timely fashion
|
|
|
|
|
many many my programs are running excellent in release but crashes at once in debug (I even can't see any interface) - I think this is microsoft's problem, we do not need to take responsibilities for it, I never worry about it at all.
So take it easy.
|
|
|
|
|
Well, if it crashes then there is a problem
|
|
|
|
|
Could you provide more information where it crashes in the debug build, including a stack trace? Is it your code or which line of the MFC source code causes the problem, perhaps it's an ASSERT?
/M
|
|
|
|
|
Since, it is a Windows Service, and I'm using MSVC6, I'm really unable to debug it.
When I call the Close method for CAsyncSocket class, the program crashes. So it seems that there is some problem in MFC's code.
|
|
|
|
|
If you are not able to attach a debugger to the process, how about a simulated stop of the service handler? Maybe write a mockup framework that would trigger your code under similar conditions. Just a guess, you are not using CAsyncSocket in multiple worker threads, everything is one thread context?
|
|
|
|
|
I call the function which is called when the SERVICE_CONTROL_STOP event is fired by myself. But I'm unable to reproduce that crash. It only occurs when it is stopped by Service Manager. No I'm not using CAsyncSocket in multiple threads

Hello,
How can i get the CPU information under VC++ (cpu modelname,cpu speed).
THNX for help!
|
|
|
|

this gives you some of the info - not sure if speed is in there ...

this from gamedev shows some interesting things - Ive seen the same method for getting the speed used before ...

In vc++ got some error.
For example error C2653: 'ELog' : is not a class or namespace name.
I can't compile it.

Hi,
I'm working on a Windows Mobile application that connects to a server on a PC.
The problem with the following lines:
CSocket as;
if(!as.Create())
MessageBox(_T("creation failed"));
if(as.Connect(_T("192.168.1.24"), 110))
MessageBox(_T("connected"));
else
MessageBox(_T("failed to connect"));
is, that Connect(...) allways returns TRUE, even if the server isn't started and even if the PC with the IP address 192.168.1.24 is switched off.
This error only occures with Windows Mobile and a WLAN connection. On Windows XP/Vista connected via WLAN/LAN or Windows Mobile connected via USB Connect(...) returns FALSE when there's no server.
Any hints?
Thanks,
Thomas
ps.: to be a bit more precise - the problematic connection is from a PDA via WLAN to a Netgear internet router and the PC is connected via LAN

Hi everybody,
I like to catch the doubleclick on the MDI Frame.
Not somewhere into the Frame, rather on the titlebar of the frame itself.
In PreTranslateMessage of the MDIChildWnd I tried already to catch the message
WM_LBUTTONDBLCLK, but it seems that this message is never handled to this frame.
Has anyone an idea?
Big thanks 
|
|
|
|
|
Knowing how frames work for normal windows, I suspect you want to look for WM_NCLBUTTONDBLCLK, i.e. the non-client area equivalent of WM_LBUTTONDBLCLK

Hai!
Is there any key in the registry which changes its value each time i install and uninstall the driver for a smart card reader!!
Thanks!
|
|
|
|
|
There are many registry settings changing. What is the purpose of this question? Why do you need to know registry modifications?
There are too many to list and some are vendor specific. Locate the driver installation package for your smartcard device and open the INF file. Registry modifications are located in the 'AddReg' sections. You can also install an installation monitor and log the registry changes.
Best Wishes,
-David Delaune
